Vesicle transport during pollen tube growth. The mature pollen proteome contains a wide range of proteins involved in vesicle transport processes (i.e., small GTPases and their regulators; SNAREs; the Rho-GDF refer to phosphoinositide-specific phospholipase C). Number of gene family members identified in the pollen proteome is listed over the total number of gene family members identified in the TAIR7 proteome. We were able to identify most of the potential members of protein complexes (i.e., Exocyst complex) shown to play a role for vesicle selection for exocytosis processes in yeast and animals. Additionally, we identified a family of proteins containing a domain of unknown function 1216 (DUF1216) that are predicted to play a role in vesicle transport.
